I have two employees. But when I try to assign them to a company, it SAYS i do not have any employees. I am set as manager of those companies and I am located in the same country. Why is this so hard to do?

If your company is not incorporated in a holding yet, you can't assign employees; so that shouldn't be the problem.

The only thing I could think of would be that you don't need employees to assign, but work units. That is, your employees need to actually have worked for you, which can be made sure of here. If you're 100% sure you have enough work units and yet can't use them to produce (obviously having made sure beforehand that you have enough raw materials if necessary), file a ticket.
